Theme is applying "hover" logic to my widget

So I've added a text widget with a javascript 'job search' box on my site. The theme is making the text in the widget box greyscale until you hover over it. I'm not sure why?

I tried disabling the greyscale image 'on hover' in the postformat - but obviously that wasn't the issue. Can anyone offer any suggestions as to the issue? it is at www dot landmaninsider dot com

Edit: It also looks like it's using the two theme colors (blue and black), instead of the colors I've defined for it. If that helps anyone narrow down where the issue might lie.
